You went to lunch with your friend and the bill was $28.00. Your lunch was $4.00 more than your friend's. How much was your friend's lunch?

A) 4f + 2=28
B) f + 4=28
C) 2f + 4=28
D) 2f - 4=28

1 answer

C) 2f + 4=28

Let f represent your friend's lunch cost. Since your lunch was $4.00 more, your lunch cost would be f + 4.

Therefore, 2f + 4 = 28
2f = 24
f = 12

Your friend's lunch cost would be $12.
